I understand your desire to change or enable web browser settings on your Samsung Intensity II. I would like to assist you with your device.

The device you have has web capabilities using a feature called "Mobile Web". It's not a full web browser, such as one you would find on a smartphone device, but does offer a limited mobile web experience. There are no options on your device to enable Javascript; however, there are web settings you can adjust. The instructions for accessing these settings are found on page 91 of your device manual, which I've included in a link here.

I trust I have answered your question, and have addressed your concern.
